i'm seriosly considering o/cing my iMac DV to 1GHz. do you think it's stable? what kind of cooling would i need? and how would i install/ power that cooling? also, does anyone know of an LCD screen they would perhaps GIVe me? or sell to me cheap? any input would be imensly helpful.

Current spec on the iMac are as follows:

processor: 400 MHz PowerPc G3
Screen: CRT
Graphix: ATY Rage 128
RAM: 640 Mb
Hard Drive: 160 Gb (iMac cut it to 130 ish)
i dremmeld a hole in the back and mounted a 12v fan inverted to suck heat out of the comp, pluss i left the clear vented handle off.
